Python - tensorflow.DeviceSpec.parse_from_string()

Last Updated : 01 Aug, 2020

TensorFlow is open-source Python library designed by Google to develop Machine Learning models and deep learning neural networks.

parse_from_string() is used to parse a DeviceSpec name into its components.

Syntax: tensorflow.DeviceSpec.parse_from_string( spec )

Parameters:

spec: It is a string of the form /job:/replica:/task:/device:CPU: or /job:/replica:/task:/device:GPU with all fields being optional.

Returns: It returns a DeviceSpec object.

Example 1:

Python3

# Importing the library
import tensorflow as tf

# Initializing Device Specification
device_spec = tf.DeviceSpec(job ="gfg", replica = 5)

# Printing the DeviceSpec 
print('Device Spec: ', device_spec.to_string())

# Getting new DeviceSpec object
new_device_spec = device_spec.parse_from_string("/GPU:0")

# Printing the result
print('New Device Spec: ', new_device_spec.to_string())

Output:

Device Spec:  /job:gfg/replica:5
New Device Spec:  /device:GPU:0

Example 2:

Python3

# Importing the library
import tensorflow as tf

# Initializing Device Specification
device_spec = tf.DeviceSpec(job ="gfg", replica = 5)

# Printing the DeviceSpec 
print('Device Spec: ', device_spec.to_string())

# Getting new DeviceSpec object
new_device_spec = device_spec.parse_from_string("replica:2 / GPU:0")

# Printing the result
print('New Device Spec: ', new_device_spec.to_string())

Output:

Device Spec:  /job:gfg/replica:5
New Device Spec:  /replica:2/device:GPU:0
